冷轧、退火工艺对SUS430铁素体不锈钢深冲性能的影响

Effect of cold and annealing process on deep-drawing of SUS430 ferrite stainless steel

  • 摘要: 化学成分、非金属夹杂物、连铸坯等轴晶率、热轧、冷轧及和退火工艺都会对材料的深冲性能有较大的影响,结合山东泰山钢铁集团有限公司SUS430热轧不锈钢带的实际生产工艺水平,将研究重点放在了冷轧和退火工艺上.通过对比分析,最终得出使用退火的热轧板、酸洗后一次冷轧并把压下率控制在80%~85%可以使冷轧成品板退火后具有优良的深冲性能.

     

    Abstract: Chemical composition,inclusions,billet equiaxed rate,hot-rolling,cold rolling and annealing process have great impacts on deep-drawing properties of the materials. Combined with the actual technology level of hot-rolled SUS430 stainless steel in Shandong Taishan Iron & Steel Group Co. Ltd.,the study focused on cold-rolled and annealing process. Through comparative analysis,it is concluded that annealing hot-rolled sheet,followed by pickling and a cold rolling with a reduction rate of 80%-85% can make the cold rolled annealed sheet product has excellent deep drawing properties.
